2 Claims. (01.146- 3) This invention relates to a juice extractor, more particularly for extracting .juice from citrus fruits.

An object of the invention is to avoid the necessity for perforations for letting the juice drain 'into the receptacle.

A further object of the invention is to provide a positioning lug conveniently positioned in conjunction with the handle so that during pouring the lug may be engaged, for instance by the thumb, so as to prevent the head falling out of the receptacle.

Further objects of the invention will become apparent in the course of the ensuing description, and will be more particularly pointed out in the appended claims.

In the drawing which illustrates my invention,-

Fig. l is a plan view of a juice extractor embodying my invention, a portion of the extractor head being broken away to permit illustration of the ledge or seat for the head;

Fig. 2 is a view partly in section and partly in elevation of the juice extractor shown in Fig. 1; and

Fig. 3 is a view principally in elevation of a juice extractor having a head of the squeezer type. In this view a portion of the receptacle is broken away to more clearly illustrate the construction of the extractor.

It has been found that for an inexpensive juice extractor a satisfactory arrangement is to mount an extractor head on a receptacle which receives the juice extracted from the fruit. The head is customarily provided with a perforated flange, and the extracted juice drains through the perforations into the receptacle below. In making ceramic articles, and particularly in making them of glass, it is inconvenient and troublesome to provide perforations, especially perforations of small size such as are required in juice extractors. I have provided a construction which dispenses with perforations and permits the extractor head to be formed with an imperforate flange or rim.

The height and general configuration of the receptacle may be such as to suit the taste or requirements of the user, the receptacle 5 shown in Figs. 1 and 2 of the drawing being provided with a pouring lip 6. The receptacle will preferably be dished as shown, and in any event will provide an annular seat 8. On this ledge or seat 8 is positioned an extractor head l8 having an annular lower rim or flange ll adapted to cooperate with the ledge or seat 8 for mounting the head on the receptacle 5.

Instead of perforating the flange or rim II, I provide for shedding the extracted juice onto the ledge or seat 8 and-draining the same downwardly through a plurality of depressions [2 formed in the seat or ledge. In the embodiments shown in the drawing substantial bearing portions l3 are provided between the depressions l2 for carrying the extractor head. It is obvious that the number of depressions I2 and the grouping of the same may be varied in accordance with differences in taste and in the requirements of the user. The depressions l2 should extend into the ledge or seat 8 sufliciently to receive juice flowing downwardly over the rim H of the extractor head. As the rim or flange II is thus made imperforate, the head is made somewhat less fragile and capable of withstanding greater pressure.

For positioning the head on the receptacle I provide in alinement with the handle IS a recess 5 for receiving a lug I1 projecting as shown more particularly in Figs. 1 and 2 from the flange or rim of the head I0. This lug l1 serves two purposes. During the extracting of juice it prevents relative rotation between the extractor head and the receptacle. When the juice is to be poured from the receptacle the handle l5 may be grasped; and by placing the thumb over the lug I1 the extractor head can be retained on the receptacle during pouring. This is of considerable advantage as in the constructions commonly employed it is necessary either to remove the head or to push downwardly on the sticky surface of the head to retain the same in position on the receptacle.

In order to provide for an even flow of juice down over the flange or rim ll of the head and onto the ledge 8, I provide for maintaining an even spacing of the rim of the extractor head from the surrounding portion I9 of the receptacle 5. Accordingly, I provide on the periphery of the rim or flange H a plurality of spaced bulges 20. I have found that a clearance of 1 3' to of an inch between the rim II and the portion I9 is suitable for permitting the juice to drain into the receptacle 5. This precise amount of clearance is not critical, however, and is subject to variation within wider limits. 7

My invention applies not only to the r-eamer type of extractor shown in Figs. 1 and 2 but also to the squeezer type shown in Fig. 3. In the embodiment shown in Fig. 3 a squeezer type of head I8 is substituted for the reamer type of head In shown in Figs. 1 and 2. With this head cooperates (as shown in dotted lines) a plunger 22 and operating mechanism 23 therefor which may be of any. suitable type. As such constructions are well known, the plunger and its operating mechanism are shown conventionally. As considerable pressure is exerted on the extractor head in a squeezer type of extractor, the sturdy construction afforded by my invention is of particular advantage for such use.

It will be apparent from the above description that I have provided a juice extractor which has advantages in ease of manufacture, in simplicity and the ease with which it may be cleansed, and in the ability to readily retain the extractor head on the receptacle when pouring the juice from the latter.

While I have illustrated and described certain preferred embodiments of my invention it will be understood that my invention may be otherwise embodied and practiced within the scope of the following claims.

I claim:

1. A juice extractor comprising a receptacle provided with an annular seat or ledge formed formed with an imperforate annular lower rim or flange for resting on said seat, said flange being sloped to cause juice to flow outwardly over the edge thereof and then beneath the same through the depressions in said seat into the receptacle, said head having a projecting lug for extending into said recess beneath the users thumb.

2. A juice extractor comprising a receptacle formed with an annular seat, and an extractor head formed with an imperforate annular lower rim or flange adapted to rest on said seat, said annular rim having spaced bulges for centering the extractor head on the annular seat, the receptacle having a handle provided with a top portion for engagement by the users thumb, and a recess extending outwardly from said seat toward the handle, and said head having a lug for extending beneath the users thumb into said recess.
